A time series of catch and effort data (1970-78) of the Ivorian purse seine fishery in Sierra Leone waters was analyzed using the Schaefer production model. The regression of C/f on effort was significant and the resulting estimates of MSY was 14640 tonnes with F msy=1734 boat days.

The 1988-1989 shrimp catch from kuwait waters was 5125 t, representing a 62% increase above the previous record of 3158 t in 1966-1967. Ninety-eight per cent of the record landing was comprised of Penaeus semisulcatus (Penaeidae). The attainment of optimal spawning-stock biomass by reduction in...

Estimates of growth parameters for Stolephorus devisi (Engraulidae) at Munda Baitground, Solomon Islands were obtained using the Compleat ELEFAN software. Also, estimates of natural and fishing mortality are presented, along with recruitment patterns. All results are presented on a per year...

Catch and effort data from the river fisheries of the Peruvian part of Amazonia are presented, and used to fit a Schaefer-type surplus production model. This suggests that present effort is in excess of what is required to generate Maximum Sustainable Yield, and that and increase in effort would...
